To all whom Be. it known that 1 XDAM Linex-:tsk ii iitizen of the UnitedStates, residing at the oitv of New York` in the hm'ough of the i Bronxand State-of New Yi-u'k.I have in vented certain newond usetul Improvements in Aniuineiators` of which the follow ing is a full. clear, andexim-t desei'll'ition.

My invention relates to annuii'ieiators und 5 inoliiilesl severalimprovements` over tlieordinary eoiistrnetions' of :iuiinni-iutois` non'in use.

'llu'l :iini luis been to so arrange the several parts as to prodiiee :icompact ande-x- 15 eeedingly sini )le strutuie. the 'reduction in 'oostot' mann aeture ot' which pre1' those of a similar type beingconsiderable.

U-)Ward increment. of said shutters is arresto by the wingsbefore mentioned. The shutter iszpivoted upon a pin 19 which extendsthrough the walls 10, and is 'provided with lips 20 which' seryeto'reta'in a signaling card insertible therebetween the shut-ter restsupon fingers or prongs 21 which extend outwardly from Athe iliigs 7,land it is hence apparent that tlieshutter movement is limited downwardlyby saidV prongs and upwa'rdly by Wings 5. The keeper is offset from the.supporting. ears 2 in the manner aforesaid in order that the termi-nalwires 22 of the electro-inagnetinay :be positioned thereunder.

The operation ot the device is as follows: Shutter 18 being in itsraised. position as shown in Fig. 1, is supported by lip 17jof thespring pressed armature. 'Upon energiz ing the` inagnet, 'tliearmaturgbeing 4drawn thereto, Wil release the shutter which fall- -ingbygravity'will engage'tlie Vsupporting vsuppo'rtlng, attaching and!llimtin van armature, an. electroifmagnet an' ter.

a variety of functions, to wit, it supports the magnet :1nd Iprovides :tpath for the magnetic flux, it affords a support for the pivoted shutterand armature, it provides supporting or securing means whereby the'device :xs u whole may he supported from n wall or other surface, andfinally affords limiting devices for the armature and for the shutter.

Whatl I claim, is:- i

l. In an annunciator, an electro-magnet. an armature, adA shutter and a.sheet; metal keeper carrying said magnet, armature and shutter, saidkeeper having supporting au electro-magnet, an armature therefor, ashutter and a sheet metal keeper carrying said magnet and armature andhaving a downwardly ydisposed limit-ing abutment for said armaturestruck np therefrom.

3. In an annuneiator, an electro-magnet, an armature, a shutter and asheet metal keeper carrying said magnet, armature and shutter andVhaving rearwardly disposed sup porting ears, upwardly disposed shutterlimiting means and downwardly disposed armature limiting means struck uptherefrom.

In Witness whereof, I .subscribe my signature, in the presence of twoWitnesses.
